Many people are familiar with such a problem: it is worth overcooling - and the lips “bloom”. Herpes - an unpleasant and even painful condition. To quickly get rid of rash, in the course go ointment. But which one to buy? What is better - Acyclovir or Zovirax (the price of the first is less)? It is not customary to save on health, but still - does it make sense to buy a more expensive tool?
Prescription and interchangeability of drugs
Both drugs belong to immunostimulants that are used topically (ointments) and oral (tablets). Their work is aimed against viruses, in particular, such unpleasant as herpes (including genital). They can also be used on chickenpox, cytomegalovirus and Epstein-Barr. Medicines are also indicated for the prevention of primary and recurrent infections that provoke Herpes simplex and Varicella zoster.
Acyclovir acts as a leading element in both Zovirax and Acyclovir. Additives matter only to those people who suffer from allergies. In Zovirax, auxiliary elements that can provoke sensitization are alcohol, paraffin, dimethicone and sodium lauryl sulfate. In tablets - lactose, povidone 30 to, starch. In Acyclovir, if we talk about tablets, additional substances 5: milk sugar, starch, aerosil, stearic calcium, polyvinylpyrrolidone.
A general contraindication is individual sensitivity to acyclovir. Side effects are similar: dermatological reactions, gastrointestinal disorders, disorders of the nervous system, headache and decreased performance.
Zovirax and Acyclovir are interchangeable drugs. They belong to the same group of medicines, have an identical effect and contain the same active ingredient. “Why, then, pay more,” you ask, because an imported drug costs 2 or even 3 times more?
The fact is that Zovirax is the original drug, and Acyclovir is a generic. The difference between them lies in the technology of production (the original undergo more degrees of purification, which means they are less toxic and not prone to cause side effects). Generics may contain impurities.
Thus, Acyclovir and Zovirax are analogues. The first is produced by Russian pharmaceutical companies, the second is made in the UK in accordance with European standards.
Generic and original drug: feel ... or do not feel the difference?
What are the main differences between the two drugs that can affect patient choice? We list the main and most important differences:
- Zovirax (in the ointment) is allowed for newborns, pregnant women (which once again confirms its high safety). The instructions to Acyclovir indicate that it should not be prescribed lactating, and during pregnancy, use is possible only in the rarest of cases (after assessing the ratio of need to probable risk). Zovirax is more often and safely discharged to pregnant women, since, according to the results of observations, he has not demonstrated a negative impact on the formation of fetal organs;
- Acyclovir can be found in the pharmacy only in the form of ointment and tablets, Zovirax is also available as a powder for injections;
- Zovirax is more expensive, but it affects the body more delicately (not to the detriment of efficiency);
Drugs of a similar spectrum
In pharmacies, you can always find a lot of similar tools; some of them are cheaper. What drugs can produce the same effect as Zovirax and Acyclovir? The analogs of these drugs are Vivorax, Virolex, Herperax, Gerpferon, Atsiklostad, Vero-Acyclovir, Gerpevir (creams and ointments), capsules - Arviron, Rebetol, Rabavin, Trivorin, Ribaleg, Alaciclovir, Ribaverin. Today, the number of such antiviral drugs is enormous.
Acyclovir or Zovirax - which is better: reviews of patients and doctors
Doctors trust Zovirax more. But, nevertheless, they often prescribe Acyclovir, especially if the patient has herpes on the face, and the area of eruptions is not too large. In such cases, the sores on the lips heal quickly - in a few days.
According to the majority of patients, Acyclovir and Zovirax act in the same way, there is no difference between them (except that the second deals a greater blow to the wallet). But still, Zovirax received a minimal advantage, as some people noticed that it helps better. Among the advantages of this particular drug, people attribute the fact that it has a thicker consistency, it is better kept on the lips (Acyclovir instantly melts). Zovirax, drying up, forms a crust on the bubbles. Under it, microbes die faster, since there is no access of oxygen and moisture.
Users indicate that it is better to use one and the other medicine at the first signs of the disease: then ointments help to get rid of the “cold” on the lips faster. Some people recommend taking a couple of pills of one or another medicine a month for prevention. Should I listen to this recommendation - you decide. But the drugs are toxic, do not forget about it!
Patients rarely mention side effects. Rather, they complain that the ointment had no effect. But this happens most often with large-scale lesions, long-term herpes infections, or if external antiviral drugs are used too often. In such situations, it is better to carry out therapy with pills or make injections of Zovirax. They will kill the virus inside the body.
So, what should be the conclusion that it is better - Acyclovir or Zovirax? If you trust domestic drugs, feel free to choose Acyclovir. If the herpes jumped on the lips or in the nose, then you should not spend large sums to purchase Zovirax. You can get along with Acyclovir - it will effectively stop the reproduction of the virus. But for the treatment of genital herpes or shingles depriving the best option is still Zovirax, because its effectiveness and harmlessness is higher.
